O Holy Spirit of God, very God, who descended on Christ at the river Jordan and on the apostles in the upper chamber, we have sinned against heaven and before you; purify us again, we ask you, with your divine fire, and have mercy on us; for Christ’s sake. Amen. Nerses of Clajes((Thomas C. Oden and Cindy Crosby, eds., Ancient Christian Devotional: A Year of Weekly Readings: Lectionary Cycle A (Downers Grove, IL: IVP Books, 2007), 135.))
